My first detector was a XLT, bought new when they first came out in 1994. I soon made up my own programs using the stock Coin & Jewelry and adding a higher Pre-Amp gain setting, higher AC and DC Sensitivity and I also like to add VCO to the trigger operated All-Metal mode. As you gain more experience with it and experiment with the settings, with it's built in "Hot Key" < or > will direct you back to your last setting to change it if you like. Very handy when experimenting with the Pre-Amp gain which is the secret to gaining depth with the XLT. With the "Hot Key" feature,...if it's set too hot it is easy to get back stability by quickly adjusting it instead of scrolling through the menu....Happy Hunting.
